Be it known that I, FREDERICK G.- SAR- GENT, a citizen of the United States, residing at Granitevillej, in the county of Middlesex,

and when the velocity of the vertical move- State ol"\lassachusetts, have invented a certainnewand useful lm rovement inVVoollll/lashing Machines, of wliich the following is aspecilication, reference being had therein to the accompanying drawings.

The invention relates to the barrow-oper- .atingmechanism of wool-,washing machines, land is more partlcularly an improvement in hrrrow-o era-ting mechanism of the type employe( in the .well-known Sargent woolwashing machines. ln the laltenas usually comtructed, the han-ow (which is moreor completely counter-balanced) derives its movement from a orank, the vin of which works in a vertical slot forme in an arm,

termed in the art a harp projectingrom Ithe barrow. As the crank rotates the crank# Apiu in moving upwardly encounters the upper end of the'said slot, raising the harrow'so as to withdraw the teeth thereof from the contents of the bowl or tank. The crank-pin supports the harrow during the upper part of its revolution, and meanwhile acts against one side-wall of the slot so as to move the harrf f endwise toward the feeding end of the bowl or tank. By the continued rotation of the crank the harrow is lowered, plunging its Y h into the contents el the bowl or tank, until trucks or rolls carried by the harrow take bearing upon tracks which are provided on the sidewalls ofthe bowl or tank, after which during the lower part of the revolu` tion of the crank the crank-pin acts against the other wall of the slot to turn the harrow lengthwise toward the delivery-end of the la,- l or tank, advancing the librous material th is contained within the bowl or tank toward the said end. The lifting oi thehan row begins, and the lowering of the same is arrest-ed, at times when the radial line ofthe crank-pin is about par allel with the barrow,

ment Wed from the cra" s at its greatest. '-fn.sequentl y, the action or the orar-lsf` pin in striking upwardly against the upper end cithe slot and suddenly lifting the harrow@1 from itsl supporting tracks occasions shock yand strain, resulting in wear and other linjury 'and shocks accompanied by injurious vconseqdenses also occur when the barrow is Mahl.

dropped upon the said tracks at the. conclusion of its movement endwise toward the acting to begin the ing movement of the harrow, andto terminatethe lowering movenient thereof, without shock, strain, wear,` and otherinjurious ellects which, heretofore have occurred. VThis object is attained by the employment, in combination 'with the harrow and itsxed arm or harp, yof means olperating with crank-action to reciprocate t e harrow lengthwise and with cam-action 7ol to roduce the vertical movements thereof.` v `he invention is illustrated by the accompanying drawings, in which latter,-

Figure 1 shows in side-elevation a portion of -a Sargent wool-washing machine with an embodiment of theinvention'a plied thefeto, the harrowbeing shown in its owestposition and advanced about halfway of its stroke-f 1 toward the delivery endof the bowl or tank.- 4 Fig. 2 is a similar view showi the barrow 80 completing the said stroke and eginning its rise. Fig. '3 is asimilar view showing the harrow in its highest position and returned half-way toward the feeding-end of the bowl or tank. -F ig. 4 is va similar view showing 85 the barrow practicallyat the termination of its stroke tou-'ard the feedingendf=-nd partly lowered. Figs. 5, 6, 7, and 8 are views-in side elevation showing other embodiments of the invention. h,

Having reference l to the drawings-I'n each of the figures, 1 ldesignates :1 -portion of the bowl or tank of a wool-washing machine, at 2 a portion of the barrow thereof, and at 3, Figs. 2 to5 and 8, the teeth ofthe 95 barrow'. At Il, 4, Figs. 1 to 7, arecross-rods forming parts of the barrow, at 5, 5 are sidearms hung by their4 upper ends to the outer ends of the said cross-rods, andat 6, .6, are armste which the lower endsof side-arms 5, 5, are hung, the said arms 6, 6, beingfast on rock-shafts 7, 7, extending transversely with respect to the bowl or tank (irrthis instance extending throu h'tubes orf'pipesset n in the opposite sidefwa ls of the sameiasin v United States Letters Patent No.l 521,823,

dated June 26, 11894) andprovided with other arms 8, 8, extending oppositelywith respect to the arms 6,: 6, thesaid-arms '8, 8, 'i

carrying weights 9, 9, 4by which the harrow and its connections are counter-balanced, the

rock-shafts being also provided with upl`wardly'-extendingyarms. 10, 10, which are linkedl t'o'getherby lconnections 11, 11to cause the counterfbalances and the dilerent and fall in unison.

At 12 is the so-called harp, located outside ille bowl or tank-and having the' upper por# portions of the`length ofthe harrow to rise ii-tion thereof fitted to the outer ends of a crossrod. 4 and to an adjacent'cross-rod 13 which 1s attached to and forms a part of the harrow. The said harp is provided for co eration l with the actuating devices from Whic move- 4and upon which the trucks 191,.19 1,carried -by cross-rods 4 and 13 rest and travel when the harrow is in its lowest position. As thus far described, the construction is or may beV substantially-as heretofore.

In. ca the inventioninto eiifect,l1 employ" in the embodiment of Vthe inventionl which isshown in 1 -to 4'," a 20,

which is connected with the earl so as toturn in unison therewith, an I rovidethe harp or arm 12 with a cam-fo ower constituted by a shoe 21, with the under face of which the said cam engages. The said cam is formed with a grade which acts against the workin'gface ofthe shoe to lift the harrow gradually' from the lowest osition of the latter, and with' another gra e' which serves to lower the harrow gradually to 'the said position again. Fig. 1 showsthe harrow in its lowest position, in which its trucks rest upon the tracks 19, and at about the middle point of its movements or traverse inthe direction from the. feeding-end of the latter. As the cam rotates from the position shown in Fig. 1 to that shown in Fig. 2 its lifting grade begins.v smoothly to raise the harrow, raising the latter part way as shown in Fig.' 2,

before the crank-pin gains on the -harrow "suii'iciently to take against the upper end of the' slot 14 in arml 12, which it does easily and without shock.-` The cran'k-pin in its continued rotation raisesv the harrow through the remainder of the lift of the' latter, and then lowers 'the same until the shoe 21- takes bearing upon' the lowering grade'of the cam, as shown in Fig. 4, meanwhile acting against i one side-wall of the slot 14 toV carry the harrow endwise toward the receiving o r feeding end of the bowl or tank. When shoe 21 the trucks or bowls again come torest upon.

tracks 19, along which they roll as the crank continues .its rotationv from the position` shown in Fig, 4, to and through that shown iiipF ig. 1. For convenience in setting the parts', shoe 2'1 is secured to arm 12 by means of bolts 22, 22, passing through vertical slots 23, 23, in the said shoe, thereby providing for vertical adjustment of the shoe upon the arm. The construction and arrangement may be varied more or less from what is shown in the drawings. Thus, the'cam may -be utilized to sup ort the harrow in its lowest position, in whic case the tracks and rollers or trucksmay be dispensed witlrl F 5 shows a construction in which the cam, 200, is constructed to raisethe harrow to its highest elevation and su port it while there, the crank acting at suoli) to' communicate Vendwise movement to the time simply harrow. A track 19 is shown, but may be dispensed with and the cam utilized to support the harrow while in its lowest position.

In 6 the cam-follower is @instituted byan anti-friction'roll, 211, bytheemploy- \ment 0f :which friction and wear are reduced, and the cam, 201,'is properly shaped to cooperate therewith.

i" At 24, in leach ofFigsyl-t'o-, is a sta rod connected at its oppositefends to the ower .endofharp 12 at substantially the point at which the' crank exerts its transverse pressure against the said harp, and to a cross-rod 4 at an intermediate point in the length -of the harrow and serving to stien the said harp, as well row to b end o r buckle.

` Fig. 7 shows a'construction embed a somewhat different form of cam, 202en- Agaging withv a shoe 21 -carried by the harp and in vwhich the slottdd lower portion of the;

harp, below the said shoe, is dispensed with,

the tie-rodbeing connected with a crank-pin,

151, carriedby the cam-disk. l Y

Fig. 8 shows a constructionl in which the a so-called three-throw eccentric 203 combining within itself the functions ofa crank in. producing the longitudinal movements of the harrow, and of a cam in raising and lowering the harrow. In Fi 6, 7 and 8, tracks 19 lalre shown but usual y will be dispensed Wit In Letters Patent N o.l 67 5,069, granted to me May 28, 1901, Ihave shown the bowl or tank provided with tracks havin raised, endportions which cooperate with t e trucks or rollers of the harrow in assisting the harrowf actuating crank in starting the rise. of the as obviate tendency' of the harharp, therein, marked 12a is furnished with a y yoke, 121, withinthe opening of-which lits harrow, and in enabling the trucks or rollers l. In a Wool-Washing machine, .or the like,

the combination with the barrow, an arm* projecting therefrom, and a crank engaging said armr and communicating longitudinal movement to the harroW, cfa. camalso en- -gaging such arm, and supporting the harrow durin' the rise and descent of the latter.

2. In a wool-Washing machine, or the like, the combination with a harroW, its slotted arm having a 'cam-follower, and a rotating crank Working in a slot'of said arm, of the i follower and operating to raise and lower v rotating cam engaging with the said follower.

3. In a machine for Washing fibrous materials, the combination With the harrow, an

arm projecting therefrom and carrying a cam-follower, a rotating crank operativelyconnected with said arm toproduce longitudinal movement of the said barrow, and a f f rotating cam engaging With the said camthe barrow.

4. In a-machine forwashing fibrous materials, the combination with the barrow, an arm fprojecting therefrom and carrying an anti iction roll, a rotatingl'crank operatively connected Wth said arm, to roduce longitudinal movement of the said arrow,

and va rotating cam engaging with the said :rolland Enperating to raise and lower the barrow.

5. In a machine for Washing fibrous materials, the combination With the harrow,.an arm projecting therefromand carrying .a cam-follower, a rotating crank operatively .connected with said arm, whereby longitudinal movement of the said harrow is produced, a rotating cam engaging with the.

said cam-follower and operating to raise and lower the harrow, and a tie-rod extending from the point at which the crank exerts its transverse pressure to a relatively remote point .in the length of the harrow.

In` testimony whereof I affix my signature in presence of two `Witnesses.
